SLIDING .AND SWIGING WINDOW.

Specification of Letters Patent.

application inea Api-i123', i913. sei-iai no. 763,005.

l Toall wiomit may concern 'Be it known that I, "Winnaar B. GATES, a citizen of the United States, andresident oi' Wilkinsbi'irg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful.Improvements in Sliding and Swinging Vlindows,cf which the following is a specilication'.

The object of this invention -is t provide simple and etlicient means for horizontally pivoting a vvertically slida'ble sash, whereby the. latter may be reversed for cleaning both sides -from within, and whereby the window niay be conveniently opened by a swinging or pivotal movement whenever such movement ispreferableto .opening the window by sliding it vertically.

A characteristicof the invention is the security `of the sash in its vertically sliding sha ed roove 6.A 50. P g

position, together with the ease and convenience with which it may be turned on its pivots.

A further object is to provide improved means for securing the sash weight connectors-chains or cords-to the sliding and swinging sash'.

In the accompanying drawings, Figure l' illustrates in perspective a fragment of i window frame with a pivoted sash tilted therein. Fig. 2 is a 'sectional plan of one side of the frame and sash, the parts being in normal or'sliding adjustment. Fig. 3 is a similar View with the sash turned on its pivots somewhat as in Fig. 1.- F ig. fl is a detail of the upper portion of one of the sash supporting channel bars. Fig. 5 is a detail of the washer arranged within the sash .supporting bar on the sash pivot. Fig. 6, is a detail of a clip, for securing a sash cord to the loop .which connects with th'e sash-carrying bar, and Fig. 7 is a cross sec-- tion of the sash-'carrying bar showing the clip of Fig. 6 in operative position.

Referring to the drawings, 2 designates the side of a window frame, and 3 are beads which form a slideway for the sash. '4 is a sash, and 5 the sash stiles having their longitudinal edge faces formed 'each with a V.-

Pivoted to each side of the sash'is a chan-- nel bar 7 which is adapted to slide between beads 13, each bar being secured to the grooved edge of the sash by a pivot-forming screw 8. The open sides of channel bar 7 are disposed inwardly or toward the sash,

as shown, and the outer side of each bai ear.

ries an apertui'ed counter-sunk plate 9 which forms a seat for head 8 of the screw, bar 7 being apeituied complementary with plate 9 so that the screw is entered from the outer side and is readily accessible when the sash and bar 7 are removed from the frame.

Confined within each bar on pivot screw S is a plate l0, the inturiied longitudinal edges 7 of channel bars 7' confining the plate therein, and the edges 10 of plate 10 engaging the opposite inner side faces of the channel bai' so that plate 10 is caused to slide freely therein on pivot 8. Plate l0 is bulged longitudinally at 10a to project through the open side of the channel bar and into groove 6 oi' the sash, the groove and the plate bulge being formed complementary' with each other to make a tight tit,

in channel 7, one end of the spring bearing against the seat 9 and the opposite end against washer 12, the latter formed with V-shaped projections l2 which tit the plate bulge, thereby holding the washer firmly seated on the pivot and at the saine time( preventing the plate l() from wabbliiig and cramping on the pivot screw when moving thereon.

In operation, springs 11 hold platelti and Y the sash normally interlocked in vertically sliding position, as in Fig. 2. To pivot the window it is simply necessary to press outwardly thereon above or below the pivot line whereupon the wedging action ofthe into the position shown in Figs. l and 3, the sash then freely swinging between channel bars 7. The frietional engagement of plates 10 with the edges of the sash serves to .hold it in any position to which it may he turned, and when the window isretui-ned to Vertical position the bulged plates snap into the V-shaped grooves 6 and securely hold the saine. It is impossible for plate 1.0 to move from posi-tion within channel-7 owingl to the y105 i inturned channel edges 7. This is rof niaterial advantage when the parts are in place las well as when assembling thern.- Also, as

the spring-seat washer is formed comple? mentary with the pressure plate and with ...waa-.ana ...r

nel bar, the latter having the inturned.

ianges, the movement of the plate toward the sash groove is limited by the flanges making it possible to accurately form the sash grooves, the maximum projection of the plate beyond the outer face of the inturned flanges being readily seen prior to making the grooves, enabling the structure to be applied to structures already in use. The outer faces of the inturned flanges provide a substantially fixed face leading to the yieldable plate 10, tending to prevent damage to the sash (an advantage Where the latter is of wood) and at the same time protect the plate as the window sash is swung. In these connections the washer 12 becomes of assistance in that the pressure of the spring is placed equally throughout that portion of the bulge with which the Washer contacts, to support the opposite pressures placed thereon as the sash rotates, a result not present Where the Washer is omitted.

For connecting a sash chain or cord to each of bars 7, the' upper portion of the outer face of the latter is cut vertically, as shown in Figs. 1 and 4, with the metal turned inwardly at opposite sides of the cut, as indicated at 14, and with the lower eX- tremities of the inturned portions notched upwardly at 14. These notches are engaged by the oppositely disposed hook eXtremi ties 15 of a loop 15. In Figs. 1 and 2, a sash weight chain 16 is shown connected to this loop, while in Figs. 6 and 7 an arrangement is shown for securing a .sash cord thereto. For the latter, the extremity of the sash cord 19 is gripped in the curved clip 17, the latter formed with barbs 1S which engage the cord when the clip is sprung into loop 15, Fig. 7. While the means here shown 'for connecting either chains or cords Copies of this patent may be obtained for ve cents each, by addressing the Commissioner of Patents.

to sash-carrying bars is simple and eflicient, it will be understood that the connections may be variously made Without departing from the invention.

1. The combination with a Window-sash having an edge groove, and a sash slideway, of a sash supporting member slidable within the slideway and comprising a channel bar having inturned flanges facing the sash, said flanges opposing each other to form a slot,v

a sash pivot carried by the bar and extending through said slot, and a spring-pressed plate housed Within the bar and having a portion complemental to the sash groove adapted to be projected through the slot into the groove, said inturned iianges acting to limit the projecting movement of the plate and to form a bearing for the sash, the bar havinga depth approximately equal to the depth of the slideway.

2. The combination with a window-sash having an edge groove, and a sash slideway, of' a sash-supporting member slidable within the slideway and comprising a channel bar having inturned lianges facing the sash, said flanges opposing each other to form a slot, a sash pivot carried by the bar and extending through said slot, a plate housed within the bar and having a portion complemental to the sash groove, a member carried by the pivot and having a face complemental to said plate' portion with its opposite face eX- tending at substantial right angles to the pivot, and a spring seated between the bar and said member and adapted to project said plate portion through the slot into the sash groove, said inturned fianges acting to limit the projecting movement of the' plate and to form a bearing for the sash, the bar having a depth approximately equal to the depth of the slidevvay.

In testimony whereof I aijlix my signature in presence of two witnesses.
